See previous thread: #173

The Travis error also occurs on master.

Yup. @topepo it looks like our builds are failing on master. The relevant errors:

checking dependencies in R code ... WARNING
'::' or ':::' import not declared from: ‘rARPACK’

* checking tests ...
  Running ‘testthat.R’
 ERROR
Running the tests in ‘tests/testthat.R’ failed.
Last 13 lines of output:
         warning = function(c) invokeRestart("muffleWarning"))
  2: eval(code, new_test_environment)
  3: eval(expr, envir, enclos)
  4: caret:::parse_sampling(i) at test_sampling_options.R:14
  5: checkInstall(pkgs)
  6: stop()

  testthat results ================================================================

The warning is solved with a simple addition of rARPACK to imports. The error looks like a test failure introduced in "added package checks for resampling"

The error occurs in the test_sampling_options.R test.

@strongh Sorry for taking so long to merge this in. Can you sync your PR and resolve any conflicts?

[strongh]

@topepo looks like it worked.

[topepo]

Can you remove theRData file from the PR?

[strongh]

@topepo it has been made so.

[topepo]

git is fighting me on merging this. I just added the files and committed (see note above) and added your contribution to the NEWS file. You can delete the PR.

Thanks for the fix!
